Multi language Date Format

Hi, I know I can format my Date Field to show what I need, but how can I change the language of the text date? In other world, if I format the date field as dddd, dd mmmm, I see Monday, 15 September. If I need this text in another language? (Italian in this case) as Lunedì 15 Settembre?
Thanks

Hi,

You may design it in your language by using UI translation:

Thanks amy, I checkedit, the line I can change in the UI translation is just reltive date informatio (like a year ago, yesterday etc…) What I need to achieve is to have name of the day and name of the months in Italian. I tried to add it in the UI translation pages under data and time, but when I save it,what I added was cleaned up
Thnks
